fabtone by Olaf Molderings

Deutschland - Kerken, Niederrhein

I have been cooperating with Olaf for a while now in the context of 3D printing. We are in constant exchange and he supports me in the further development of 3D printing.

Together with him, I also designed the inlays for the mouthpiece set packaging, for example.

With his company fabtone, Olaf has developed super exciting and special saxophone mouthpieces. Feel free to have a look there.
